| Which plan to pick | Start on Ahrefs Free to audit your own site. If you want to research competitors and keywords every week, go straight to Lite; the Starter plan's credits run out too quickly to be useful for more than the odd lookup. Each plan includes one user, and extra seats cost $40 to $80 a month. | There's only one way to pay. Use the $1 trial credit to test the MCP server, then top up $50 and set a daily limit of a dollar or two. Use the cheaper standard queue for bulk jobs and the live mode only when you need an answer now. | The free version is enough for most small businesses because it includes every feature and only caps the crawl at 500 pages. Buy a licence when your site or your clients' sites go past that. The price is listed in pounds with dollar and euro options at checkout. |
